| 摘 要： | 根据超声空化原理,运用声致发光成像技术测量超声在液体中的动态分布。利用高灵敏度的ICCD成像系统记录水在超声作用下的声致发光图像,并且分析了声致发光的分布和强度与作用超声的关系。结果表明,超声作用下的发光图像能够反映该作用超声在水中的分布情况,从而提出利用声致发光成像技术测量液体中超声场的分布是一种动态测量声场强度的新方法。

| Abstract: | A sonoluminescence(SL) imaging method based on ultrasonic cavitation is employed to determine the distributing intensity of ultrasound in liquid. A high-sensitive ICCD imaging system was used to record the SL image resulted from ultrasonic cavitation. The relationship between the SL intensity and ultrasonic intensity was studied. The results show that the SL image can reflect the distribution of ultrasound, accordingly, the SL imaging can be considered a method to measure the intensity of ultrasound dynamically. |
